I wore Merrell for years and the jungle mocs are the best of their slip-in shoes for comfort and long distance walking. My last pair lasted 5 years and I was able to walk them in snow and rain for so many miles with a different insole. This is the first time I'm trying the non-waterproof jungle mocs. They feel exactly like the waterproof one.The arc and heel support is very good. It fits snuggly but stretchable enough for my wide feet. I normally wear 8.5 wide on other brands, and the 9 fits me after I break it in. The bottom of the shoe feels well cushioned and helps walking for miles. The insole is kind of plain, so I use a thicker gel insole to make the shoes feel perfect. These aren't waterproof, so I'm going to apply sno seal on these.I normally wear the slip-in New Balances and Sketchers because of how comfortable they are for long walks and standing awhile. These shoes are slightly less comfortable than Sketchers with the yoga mat insole, but more supportive than the Sketchers and New Balances. It is also the most durable and traction of my shoes that aren't boots.My only criticism of these shoes is that they are aren't stylish or normal looking enough for me. It's kind of ugly with the checker heel and sides of the treads. I can't wear these shoes for formal/semi-formal events. I wish Merrel would make shoes this comfortable that look like shoes that can be casual or used for events.I really love these shoes and I own multiple in different colors. I'm definitely getting more of these.
